Answer:
8
Step-by-step explanation:
Answer:
X= 9/2
Alternative form
x=4 1/2, x=4.5
Step-by-step explanation:
*= Multiply
1. log (little 10 under) (2)*(3x-1)= log (little 10 under) (2)*(x+8)
2. then divide both side by log (little 10 under (2))
3. 3x-1=x+8
4. move variable to the left side and change its sign
5. 3x-x-1=8
6. then move constant to the right side and change its sign
7. 3x-x=8+1
8. collect like terms
9. 2x=8+1
10. add 8+1
11. 2x=9
12. then divide both sides by 2
13. 2/2 9/2
14. 2/2 cancels out so x=9/2 is the answer
Answer:
x = 17/2
Step-by-step explanation:
x-3 x+8
------ = ------------
2 6
Using cross products
(x-3) *6 = 2 (x+8)
Distribute
6x - 18 = 2x+16
Subtract 2x from each side
6x-2x-18 = 2x-2x+16
4x-18 = 16
Add 18 to each side
4x-18+18 = 16+18
4x = 34
Divide each side by 4
4x/4 = 34/4
x = 17/2
Answer:
Decimal: 5.66478
Step-by-step explanation:
√6 + √11 / √5 + √3
= √3 + 1/5 √55 + √6
Step-by-step explanation:
Given the expression that Tayler tried to evaluate as:
We will solve this equation using PEDMAS
Multiplication before addition and subtraction
On solving:
From the steps above, we can see that Tayler made an error in step 3 by taking the difference of 7 and 6 and arriving at 1 instead of summing up to get 13 as shown above.
